NiMH battery charger chip EW78P259NSO14J

Opened a Sanyo NC-MQN06U Ni-MH battery charger. The charging seems to be done by 4 half-watt resistors and a 14-pin SMT chip : EW78P259NSO14J. Does anyone have any information about that chip ?



There is an EM78P259N micro-controller by Elan but it has 18 or



20 pins.

Thanks in advance.

Even if you could get the a blank chip, the manufacturer of the charger would not give you the program. Requesting a chip from the charger manufacturer will probably get you no ware. Buy a new charger dude! Shaun
